Answer:-

1.Sol:- (2)

Let number be 81a and 81b
Now
81a + 81b = 1215
= a + b = 15
Number are 81 x 7 = 567
And 81 x 8 = 648
Required sum = SSC-CGL-MATHS-QUIZ-20-01-2020

2. Sol:- (2)

Let teacher’s age is x year
Total age of students = 24 x 15.5 = 372
SSC-CGL-MATHS-QUIZ-20-01-2020
24x = 972
= x = 40.5
Sum = 372 + 40.5 = 412.5 year

3.Sol:- (3)

Let number be x
ATQ,
(38 % - 22 %) SSC-CGL-MATHS-QUIZ-20-01-2020 x = 32
16% = 32
1% = 2
17SSC-CGL-MATHS-QUIZ-20-01-2020 % = 35

4. Sol:- (3)

A : B = 1 : 4
Late rate = x%
SSC-CGL-MATHS-QUIZ-20-01-2020SSC-CGL-MATHS-QUIZ-20-01-2020
SSC-CGL-MATHS-QUIZ-20-01-2020 = SSC-CGL-MATHS-QUIZ-20-01-2020
SSC-CGL-MATHS-QUIZ-20-01-2020
Applying C & D rule
SSC-CGL-MATHS-QUIZ-20-01-2020

5.Sol:- (2)

MP/CP = (100 + P) / (100 – D)
MP/CP = 8/5
Let MP be 800x
And CP be 500x
After increment,
New C.P = 600x
After 20% profit SP = 720x
Discount percent = 10%

6. Sol. (1)

Slope of the line 20x + 5y = 3
SSC-CGL-MATHS-QUIZ-20-01-2020
Slope of line perpendicular to line 20x + 5y = 3
SSC-CGL-MATHS-QUIZ-20-01-2020
If two lines are perpendicular then:
SSC-CGL-MATHS-QUIZ-20-01-2020

6. हल. (1)

रेखा 20x + 5y = 3 की प्रवणता
SSC-CGL-MATHS-QUIZ-20-01-2020
रेखा, जो  20x + 5y = 3 के लम्बवत है उसकी प्रवणता:-
SSC-CGL-MATHS-QUIZ-20-01-2020
यदि तो रेखाएं एक दुसरे के लम्बवत है तो :-
SSC-CGL-MATHS-QUIZ-20-01-2020

7. Sol. (2)

SSC-CGL-MATHS-QUIZ-20-01-2020
Then = SSC-CGL-MATHS-QUIZ-20-01-2020

8. Sol. (1)

SSC-CGL-MATHS-QUIZ-20-01-2020

8. हल. (1)

SSC-CGL-MATHS-QUIZ-20-01-2020

9. Sol. (4) SSC-CGL-MATHS-QUIZ-20-01-2020
SSC-CGL-MATHS-QUIZ-20-01-2020

9. हल. (4) 


SSC-CGL-MATHS-QUIZ-20-01-2020
SSC-CGL-MATHS-QUIZ-20-01-2020


10. Sol. (1)

Let internal angle = 5x, external angle = x
SSC-CGL-MATHS-QUIZ-20-01-2020
Number of sides = SSC-CGL-MATHS-QUIZ-20-01-2020

10. हल. (1)

माना आंतरिक कोण = 5x, वाह्य कोण = x
SSC-CGL-MATHS-QUIZ-20-01-2020
भुजाओं की संख्या = SSC-CGL-MATHS-QUIZ-20-01-2020
